1. A system for reducing a dark period between successive data acquisition periods associated with the detection of one or more target molecules hybridized to at least one of a plurality of probes disposed upon a biological probe array, comprising:

  • a switch that alternately directs an analog signal between a first circuit and a second circuit, wherein a period of time is required to alternate between the first and second circuits and the period of time includes a dark period;

    a first integrator associated with the first circuit that integrates the analog signal to generate a first integrated value;

    a second integrator associated with the second circuit that integrates the analog signal to generate a second integrated value; and

    an analog/digital converter that produces a digital value for each of the first integrated value and the second integrated values wherein the signal from the first and second integrated values are our of phase to reduce the dark period.
